Quotes:

“Do we really hunger for the kingdom to come in all its surpassing righteousness? Or would we rather waddle through a swamp of insincerity and unrighteousness?”

D. A. Carson in Jesus' Sermon on the Mount

“It would seem that Our Lord finds our desires not too strong, but too weak. We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered us, like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at the sea. We are far too easily pleased.”

C. S. Lewis in The Weight of Glory
